To all whom il may concern:

Re it known that l, FRANK Somer, n. cit-izen of the United States,residing in `lloila` dolphin, Pennsylvania, have invented certainimprovements in Trunlolioolrs, of which the following is uspecification.

My invention relates to eerteiii improve-- monts in locking mechanismused particularly on boxes, chests, document enses and lil/Ie articles.

@ne object of the invention'is to provide :i simple and effective, lochvin `Which the look proper is independent oi the bolt.

Another object of the invention is to so eonstrnot the' lock that thebolt mechanism Will return the tumbler to its originel position os soonreleased from the control of the key, and u still further object isto'sov Width equal to the combined Width Ot thebolt C and the dog D andthe endof this projeetion rests against the rear end of the dog when incertain positions. The dog-is notched :it d2 to form a projection dwhich either rests upon or engages the lug o2 on the bolt. l

j is a spring mounted on one of thepins... o2. @ne erin oi' the springrests -against n pin 03 on the bolt C and tends to move it forward whilethe other arm rests against, a. pin al* on the dog D and tends to pressthe donl down.

lllfhe'n the )arts are in vthe looked as shown in ilig. l, the notcheden of the projections l) of the keeper are in engagementnilh the boltand one of the projectionsl also rest-s against the rear portion of thedog` D, holding in engagement CPosition,

be impossible to yjar the bolt-loose lifter it is thrown to theloclredposition.

' In the accompanying d1'aiving:-Figure l, is e sectional yiew of a.metallicjboxillustrating my improved locking mechanism; Fig. 2l, is eview oi? the lock mechanism showing the keeper retracted; Fig. 3, is aview showingr the keeper in line Wit-h thevbolt; the bolt being held bythe raised tumbler of the lock; Fig. fl, is a sectional plan View on thelino #iw-fl, Fig. l; Fig. 5, is o. perspeetiye View of the bolt; Fig. 6is o 1mrspeotive View of bolt cannot. be j erred out of engagement, butas soon as the dog is raised, on the movement of the lever 3, it will belifted'cleztr of the lug c2 as it'will slide on its pin d; the ends ofthe Aprojection I) becoming the fulcrum and the bolt will thus bereleased. Un the continued movement of the lever E, it will move thebolt C longitudinally clear ot the keeper B. The lock pro-per G ispreferably made independent of the bolt, as shown, so that any type oflook may be used in combination with the bolt. The casing of the look Gis made from sheet metal as shown in Fig. 8. On the casing is theT-l1eeded projection L which passesthrough on opening al in the tumblerl; the tumbler having a. shoulder a" engaged by -the projection 7i. Thelower end of the tumbler is guided by a. projection which is nd'eptedtoa slot 2 in the tumbler. A spring /c 1s secured to the tumbler, as shownin Fig. 9, and presses casing; tending to force the tumbler toward thekey hub. This key hub m is mounted in the casina;r and on the tumbler isthe projeoftion 1'3 which passes over the hub and -a shoulder 4 which isengaged by the key when it is inserted in the key head and turned.v Thetumbler rises from the tion illustrated in Fig. l to thlat illustratedview or' the lever; Fig. 8, is u perspective A is the body of anordinary metallic document euse and A is the lid hinged to the box in'the usual manner. Secured to the flange of the lid A is thel keeper Bhei/ine` hooked projeotions b which extend through openings a in thebolt easing` a in the pres ent instance.

C is s bolt having three hooks o engaging the hooked projection Aof thekeeper and this bolt is slotted at c end through the slots pass pins asecured to the casing. These pins hold the bolt in proper position andallow it to freely slide into either the open or closed position.

D is e locking dog made asshown in Fig. @having an elongated pivot pinopening d for the pin a so that it can rock and slide upon said pin. Thedog has a heed d provided -with on inclined surface against against theK central projection l) of the keeper B is of e' the do with'theprojection da. Cgonsequently, the

posieer is located directly vin line With the in Fig. 3, by turning thekey.

vspring j and the dog will ride upon the lng, but

when Athe keeper is inserted on closing the box, the bolt and the dogwill be pushed back by the projection Z) on the keeper and theprojection d3 of the dog will drop back of:` the lug c2 and hold thebolt in position es shown in Fig. l. On the movement of the boit by 'thespring f it will act upon the lever E, which in turn will force thetninA hier into theposition shown in Fig. l.

lt will be understood that the locir may he modified without departingfrom the essential features of the invention.

By the use of my invention l can make a very simple lock which can haveone or more hooked projections which may engage the hooked projectionson the keeper. The lock is preferably made as a snap loch; the boltbeing entirely independent of the main lock mechanism which 'can be oiany type. lhe type shown in thel drawings is very easilfvv andeconomically made.

The slot in the dogmiist be so proportioned that the distance betweenthe pin and the 'rear end of the slot must be less than the Width of the.keeper projection so that even l if the bolt should move longitudinallywhen the bos. is jarred the dog Will prevent the inll moveinent of thebolt owing to the end i of :the slot in the dog coming in contact withthe pin, thus preventing the opening of the box.

I claim:

l. llhe combination ot 'a heepena sliding bolt adapted to engage thekeeper, a pivoted locking dog engaging the bolt and arranged tobe actedupon by the keeper, a si ring actuated lever for throwing the bolt "andlifting the dog,l and a tumbler engaging the lever. Y i

2. The combination in a lock, of a keeper, having a Wide hookedprojection, a sliding bolt for the hook arranged to be engaged by theprojection on the keeper, a pivoted locking dog arranged to be actuatedby the hooked projection and having a projection engaging the lug on thebolt and the locking dog, and a separate locking mechanism for actuatingthe lever.

3. The combination. in a lock, of a keeper having a series of hookedprojections, a easing,-a sliding bolt mounted in the casing and' havinga series ohooks to engage the projections of thelreeper; a pivotedlocking dog engaging the bolt when in the forward position and arrangedto be acted upon by one ot the proiections of the keeper, said bolt anddog being notched, a two-armed. lever pivotally mounted in the casingand having one arm extending into the notches of the lever and dog, witha separate'locl casing, a tumblentherein bearing against the other armof the lever, and means for actuating the tumbler.
